Migrate @solana/react to depend on @solana/kit (peer) and re-export @solana/subscribable from kit

Switches `@solana/react` from pinning each consumed Kit sub-package individually to a single `@solana/kit` peer dependency. Promoting Kit to a peer means apps that depend on both `@solana/react` and `@solana/kit` get one deduplicated Kit instance — important for anything relying on shared types and `instanceof SolanaError` checks — and lets consumers upgrade Kit independently of React within the peer range. Mirrors the convention used by Solana program clients.

To support a single import root, this branch also adds `export * from '@solana/subscribable'` to the `@solana/kit` barrel. The reactive store types (`ReactiveStreamSource`, `ReactiveStreamStore`, `ReactiveActionSource`, etc.) and helpers (`createReactiveActionStore`, `createReactiveStoreFromDataPublisherFactory`) were already needed by anyone consuming Kit's `PendingRpcSubscriptionsRequest.reactiveStore()` — promoting them onto the Kit surface formalises that.

Every `import { … } from '@solana/subscribable'` (and the remaining sub-package imports) in `packages/react/src/**` is rewritten to `from '@solana/kit'`. No behaviour change beyond the dep-tree shape; `@solana/kit` itself depends on the same sub-packages.

`@solana/promises` stays a direct dep — it's a small utility not part of Kit's public surface.

+Migrate `@solana/react` to depend on `@solana/kit` as a peer dependency (replacing its individual workspace sub-package deps) and re-export `@solana/subscribable` from `@solana/kit` so React consumers have a single import root. `@solana/promises` remains as a direct dep — it's a small utility that isn't part of Kit's public surface.
+
+For `@solana/react` users:
+- `@solana/kit` must now be installed alongside `@solana/react`.
+- Apps that already use both get a single deduplicated `@solana/kit` instance — important for anything relying on shared types or `instanceof SolanaError` checks.
+- Kit can be bumped independently of React within the peer range.
+
+For `@solana/kit` users:
+- `ReactiveStreamSource`, `ReactiveStreamStore`, `ReactiveActionSource`, `ReactiveActionStore`, `ReactiveState`, `createReactiveActionStore`, `createReactiveStoreFromDataPublisherFactory`, `DataPublisher` and the rest of `@solana/subscribable`'s surface are now reachable directly through `@solana/kit`.
